This is very useful. Thank you, Cheetah Mobile, for making this app that gets rid of junks. Now my most favourite game worked smoothly. This should be the very first app on your tablet, iPad, etc. You just gotta make sure no virus are occurred first before downloading apps. I am in love with this game! Those who rate 🇴🇳🇪⭐, they are messing out. Best app ever, Cheetah Mobile. 👍

Can't understand that what is going on with this App. After every operation there are 2 advertisement. Are you providing free app or Earning trillions via advertisement. If you are providing this App as a default app with phone manufacturer then you must stop such adds or stop making foolish to phone manufacturer. This is serious issue which can be raised to International Courts, which you are fooling to customers

Update: so CM responded and I sent them an email explaining the issue further. They released an update for the app, but I'm still having the same issues. Unlike other cleanup apps, this works. However, it seems like every time it updates, it takes a while before the app actually cleans anything. I would often have to do it manually in my settings.

I've used this app for years and liked it. It does what is supposed to. But it sends too many damn notifications and asks for too many permissions. I'm about to uninstall it. UPDATE: Your reply to the above, suggesting that I simply turn off the notifications in settings, is infuriating. I have notifications turned off. Cleanmaster keeps sending notifications telling me to turn on notifications as as well as constant reminders to run the app. It never stops. Also, there are now way too many ads. Close one and another one pops up. It now takes to too long to clean my phone using this app.

The app actually has revived my note 4. Before the battery would die within 3 to 4 hours despite being a brand new battery. Now with hibernating apps it brought back the 7 to 8 hour life. It also freed up 3 GB of storage for me. All around great app just don't give it 100% access to everything as that ended up slowing down my phone again. Thank you

Lot of adds make it very irritating to use this app. I am reviewing after almost 2yrs, 2yrs back i complaint abt add, 2yr since then adds has increased. No use of our feedback Still the same Clean Master. No change. Lots of Adds make it frustrating to use.

Does its job, cleans temp cache from apps left on cell internal and cools down the phone by closing apps running in background + a malware/sensitive scanner. Also has an Uninstaller, multiple apps can be Uninstalled same time or move to SD card option. Works like a charm

I'VE USED THE WHOLE OF CLEANMASTER AND HAVE STAYED WITH IT WHICH WITH ME SAYS, IM IMPRESSED. WHAT STOOD OUT MOSTIS THE EFFICIENCY OF THE ANTIVIRUS MODE, I'VE YET TO FEEL ANYTHING BUT SAFE. ONLY APPLICATION I'LL USE.

I've been using CHEETAH MOBILE products since getting my 1st smartphone, only 3 yrs ago. The full suite of products (including SECURITY Master, CLEAN MASTER , ETC), have been nothing short of FANTASTIC for me. I used double security coverage for almost 3 years and just recently made the decision to dump my other security pkgs. In favor of CM. The only other coverage I keep is strictly for services CM does not currently offer. I just upgraded to their premium SECURITY MASTER and consider their cost reasonable ($36 US). I DO wish they could find a way to offer multiple device discounts, as I'm responsible for security on 4 portable devices, but that's my only true "worry at this point.

Whenever I use the boost function of your app, I notice that it does not even empty the app cache. For instance, I just used Clean Master 10 minutes ago. Before I pressed the "boost" function, my Opera app had 134 megabytes in the cache. After using the boost function, my Opera app STILL had 134 megabytes in the cache. So clearly, your app DOES NOT WORK as promised. I have absolutely no idea why it has a 4.7 star rating. It's a mystery to me. Please explain to me why your app says it's cleaning the cache when it is NOT.

Hi,
Thanks for using Clean Master. To deal with this problem, please turn on Clean Master in accessibility( Setting,System,Accessibility ). If you have any other problems, please send us more details via Clean Master, Me, Feedback. We will help you deal with it. Thank you.

Hi,
Thanks for using Clean Master. Sorry for the inconvenience. Could you update to the latest version, we made some improvements, if it still doesn't work on new version, please feel free to tell us more details via Clean Master, Me, Feedback, we will look into it. Thank you.

Michael Brooks September 24, 2017

Overall pretty good. But I think it is trying to do too much and has too many "features" that may bog it down. Getting rid of the junk I think will improve it.

Works well but you have to put up with excessive amounts of adverts. Note: the Lite version is best for budget phones, not this one!

Hi, so sorry for the trouble! We have send your suggestions to our product department, they will seriously consider them. Now we recommend you the Clean Master lite, it is simple and clear for mobile. Any question, please contact us at client@cmcm.com.

September 24, 2017

It's amazing and my phone was lagging and crashing before but bow it runs really smooth and clearly! I would definitely recommend this app!

Hi,
Thanks for using Clean Master. To help us solve the problem, could you send us two screenshots ( 1. Setting, Battery, Battery usage including Clean Master battery consuming status. 2.

Does it job without questions but would be even much more better if the widget would appear a bit sleek and with detailed info in it... Thanks guys. Good job

Too many ads, full-screen and not obvious how to clear. Also Don't like that it is always trying to get the battery charger app enabled which I found useless and just gives more opportunities for even more ads!

Saved me from 5.8 gigabytes of wasted space, a real hero, easy to use and by far the best cleaner app. Clean master is the true master!

"Application Clean Master it is best also,but it sometimes it becomes too difficult and heavy when I want to open it., "So,.,I hope very-very much to the part of the management of Clean Master is able to further Improve the Quality and speed on this Application.,if there are still more the same problem this happened to me after this.,I will promise that I will immediately BøYCøTT the app Clean Master this until to the end of the breath I'm in this world..!!!✌😯✌ ("Dø Yøu UndêrstøøD øR Nøt Dude??) ✌😎😠😎✌ #Hopefully

Easy to use Free App. But the ads should be clearly separated from the tools. They are too integrated into the design. And, ironically, the program takes up too much space for something that's purpose is to free-up internal space. How about compressing the program's files a little better for efficiency?

Does a goo job, BUT If I listened to it, I would never get a chance to use my tablet. It is worse than Windows in that regard. Uninstalling.

Dear user, firstly you need root you phone. And then you can find this function entering the Phone boost page. Then pls click the tree points on the right top corner. There you can find Autostart Manager. Thank you.

Something called "CM Secure Connection" keeps switching itself on. I already have a VPN app, thanks, but I have no idea how to keep this CM thing off. Also I'm sick of it banging on about "junk notifications". I have the notifications that I want.
